The Q is a little high. Some of the other options have a little better response curves IMHO. See the graph below.

Pretty much anything except opera and country.

Even if we overlook that there doesn't seem to be enough excursion to take the full 500W and graph its response exceeding xmax, it doesn't seem like there's an argument for it over some of the other driver options (which can take the full 500W) that are in the same general ballpark on cost.

We've got 4 drivers that perform pretty much identically (with 1dB) from 10Hz to 40Hz in a 45L box with 500W (assuming the Dayton 12" HF has more than the rated xmax). Above 40Hz some differences appear.

Are you completely sold on sealed? I'm still not sure exactly what your goal is with this sub, but I just checked out the 10" dayton ultimax in 45l with a CSS APR15 +900g mass. You end up with a box that's flat to 23hz and handles the 500 watts no problems

I'm not 100% sold on sealed. I am pretty much sold on 45L or really close to it.

Well it will in the box. In terms of the graphs from Unibox it's not that hard to ignore the portion above 100-125Hz. Adding a HPF and the LPF for Unibox isn't trivial since it only supports one .frd file and they're a pain in the butt to synthesize.

I think I will probably go with the 15" Dayton HO, but I may wait for it to go on sale. If I go with the SI HT 15" D2 I will find myself with an uncontrollable desire to get a more powerful amp instead of the 500W Yung since the driver is loafing along with only 500W.
